The Platform library is a small C99 library that implements the native methods required to run an application. This includes a small rendering API, image and font loading, and window & input management.

The repo already contains prebuilt binaries for 64-bit Windows/Linux/macOS, but you can also build it yourself using CMake:

mkdir build
cd build
cmake ../
make

If built successfully, the library should appear in libs/{yourPlatform}, which is then used & copied from Framework/Foster.Framework.csproj.
